To demonstrate properties of the International Classification of the External Cause of Injury (ICECI) as a tool for use in injury prevention research.
The Childhood Injury Prevention Study (CHIPS) is a prospective longitudinal follow up study of a cohort of 871 children 5-12 years of age, with a nested case crossover component. The ICECI is the latest tool in the International Classification of Diseases (ICD) family and has been designed to improve the precision of coding injury events. The details of all injury events recorded in the study, as well as all measured injury related exposures, were coded using the ICECI. This paper reports a substudy on the utility and practicability of using the ICECI in the CHIPS to record exposures. Interrater reliability was quantified for a sample of injured participants using the Kappa statistic to measure concordance between codes independently coded by two research staff.
There were 767 diaries collected at baseline and event details from 563 injuries and exposure details from injury crossover periods. There were no event, location, or activity details which could not be coded using the ICECI. Kappa statistics for concordance between raters within each of the dimensions ranged from 0.31 to 0.93 for the injury events and 0.94 and 0.97 for activity and location in the control periods.
This study represents the first detailed account of the properties of the ICECI revealed by its use in a primary analytic epidemiological study of injury prevention. The results of this study provide considerable support for the ICECI and its further use.
证明国际损伤外部原因分类（ICECI）作为一种用于损伤预防研究的工具的特性。
儿童损伤预防研究（CHIPS）是一项对871名5至12岁儿童队列进行的前瞻性纵向随访研究，具有嵌套病例交叉成分。ICECI是国际疾病分类（ICD）家族中的最新工具，旨在提高损伤事件编码的准确性。研究中记录的所有损伤事件的详细信息以及所有测量的与损伤相关的暴露情况均使用ICECI进行编码。本文报告了一项关于在CHIPS中使用ICECI记录暴露情况的实用性和可行性的子研究。使用Kappa统计量对受伤参与者的样本进行评分者间信度量化，以测量两名研究人员独立编码的代码之间的一致性。
在基线时收集了767本日记，以及563起损伤的事件详细信息和损伤交叉期的暴露详细信息。没有无法使用ICECI进行编码的事件、地点或活动详细信息。对于损伤事件，各维度内评分者之间一致性的Kappa统计量范围为0.31至0.93，而在对照期内活动和地点的Kappa统计量分别为0.94和0.97。
本研究首次详细阐述了ICECI在一项损伤预防的主要分析性流行病学研究中的使用所揭示的特性。本研究结果为ICECI及其进一步应用提供了相当大的支持。
